I have an EX-141, and when I want to add an exception to the firewall, I need to pass the entire IPv6 of my device on the router. Its lower parts of the IP are fixed, because its local, but the higher part is global and changes based on the ISP.

I cannot use wildcard on this router to signal the global part and then use only the local part. What would be the cheapest router I can get that supports this feature?
